Mitech MHV-Z Series Automatic Turret

Mitech MHV-Z Series Automatic Turret Hardness Tester

Product Overview

The Mitech MHV-Z Series Automatic Turret Hardness Tester is a precision Vickers hardness testing instrument engineered for micro and macro hardness measurements on metallic and non-metallic materials. Utilizing a diamond pyramid-shaped indenter, this system produces an indentation on the test surface, from which the diagonal is measured to calculate hardness values.

Equipped with a motorized automatic turret, high-resolution optical system, adjustable cold light source, and electronic load control, the MHV-Z Series delivers consistent and efficient hardness testing. Its robust design and automated functionality make it ideal for industrial manufacturing, materials research, and quality assurance environments.

Key Features

• Automatic turret allows seamless switching between the indenter and optical lenses for increased testing efficiency

• Electronic loading system eliminates the need for manual weights, ensuring consistent force application

• Adjustable cold light source provides optimal visibility with minimal thermal impact, controlled via software

• Large LCD screen clearly displays test results and enables user-friendly menu navigation

• High-precision optical and photoelectric sensor system ensures accurate test point positioning and readings

Working Principle

The Vickers hardness test method involves pressing a square-based pyramid-shaped diamond indenter into the specimen’s surface under a specific load. After holding for a defined time, the load is removed and the diagonals of the resulting indentation are measured under a microscope. Hardness is calculated using the formula:

HV ≈ 0.1891 × F / d²

Where:

• HV = Vickers hardness value

• F = Applied force in newtons

• d = Average of the two diagonals of the indentation in millimeters

Operating Conditions

• Temperature range: 18–28°C

• Relative humidity: ≤ 65%

• Environment: Should be vibration-free, dust-free, and free from corrosive gases

• Installation: Must be placed on a flat, stable surface

The Mitech MHV-Z Series offers a comprehensive solution for advanced hardness testing with high accuracy and automation, suitable for a wide range of industrial and research applications.
